Mythology & Beliefs: IphigeniaIn Greek and Roman Mythology, Iphigenia was the daughter of Agamemnon; offered as sacrifice to Artemis
at Aulis; carried by Artemis to Tauris where she became priestess; escaped from there with Orestes.

Iphigenia in WikipediaIphigenia (pronounced /ɪfɨdʒɨˈnaɪ.ə/; Greek Ἰφιγένεια,
Ifigeneia) is a daughter of Agamemnon and Clytemnestra in
Greek mythology.[1] In Attic accounts,[2] Her name means
"strong-born", "born to strength", or "she who causes the
birth of strong offspring."[3] Artemis punished Agamemnon
after he killed a deer in a sacred grove and boasted he was
the better hunter. On his way to Troy to participate in the
Trojan War, Agamemnon's ships were suddenly motionless, as
Artemis stopped the wind in Aulis. The soothsayer, Calchas,
revealed an oracle that appeased Artemis, so that the
Achaean fleet could sail. This much is in Homer, who does
not discuss the aspect of this episode in which other
writers explain that the only way to appease Artemis was to
sacrifice Iphigenia to her. According to the earliest
versions he did so, but other sources claim that Iphigenia
was taken by Artemis to Tauris in Crimea to prepare others
for sacrifice, and that the goddess left a deer[4] or a goat
(the god Pan transformed) in her place. The Hesiodic
Catalogue of Women called her Iphimede/Iphimedeia
(Ἰφιμέδεια)[5] and told that Artemis transformed her into
the goddess Hecate.[6] Antoninus Liberalis said that
Iphigenia was transported to the island of Leuke, where she
was wedded to immortalized Achilles under the name of
